The campaign to turn part of the Trent Park Mansion into a museum has made some very significant progress towards its goal.  The planning application submitted earlier this month by Berkeley Homes envisages most of the ground floor and basement being reserved for public use - a museum, cafeteria and rooms for hire.  The museum would celebrate the mansion's notable role in WW2 intelligence collection and its previous history as an aristocratic residence.

Cockfosters Ward Councillor Jason Charalambous, a leading figure in Save Trent Park, has expressed satisfaction with the outcome of its campaign.  As well as providing for an adequately sized museum and, for the first time, public access to parts of the Mansion, the campaign has succeeded in persuading Berkeley to allow continued public access to the grounds of the former University.

Councillor Charalambous also has positive views about Berkeley's proposals for the rest of the former university site, which would restore heritage features and landscapes that have been neglected.  The 262 homes proposed would, in his view, be "sympathetically designed and located".

Berkeley Homes carried out an extensive public consultation process to help develop proposals which would find favour with local residents and regular visitors to Trent Park.  Since last December they have held four two-day consultation events and have announced a fifth and final event, to be held at the West Park Lodge Hotel on 4th and 5th November, when project team members will be available to answer questions and visitors will be able to view the plans that were submitted.

Whether the scheme goes ahead exactly as proposed will, of course, depend on its receiving planning permission from the Council.  This is a large and complex scheme on a sensitive site surrounded by Green Belt land, so there will be much for the planning committee and its officers to consider.  As with all planning applications, members of the public will be able to raise objections to the plan in whole or part.

For Save Trent Park and for the Trent Park Museum Trust, planning permission will by no means be the end of the story.  They will need to negotiate a workable lease from Berkeley and secure the necessary funds, but they are optimistic that within a few years they will have established "a local attraction of national significance".

This morning's Today programme on Radio 4 included a very interesting interview with Helen Fry and Helen Lederer about the Secret Listeners and the Trent Park Museum project.

Go to . The interview starts 1 hour 20 minutes in.

There's a chance to see and hear Helen Fry talking about the Secret Listeners on Saturday 15th October in Southgate. This is a not-to-be-missed talk!
